Y5-48 boiler-induced draft fan introduction
Y5-48 centrifugal induced draft fan is also known as "Y5-48 boiler induced draft fan" and "Y5-48 boiler centrifugal induced draft fan".
Y5-48 boiler-induced draft fan is an induced draft fan with a maximum total pressure efficiency of 91% designed for industrial boilers with a processing capacity of 1 ton to 20 tons per hour using various fuels and equipped with smoke suppression and dust removal devices. Those with similar inlet conditions and performance can be selected, but the maximum temperature shall not exceed 250 ºC, Before the induced draft fan, a dust removal device with an efficiency of no less than 85% must be installed to reduce the dust content of the flue gas entering the fan and improve the fan life. The induced draft mechanism is of single suction type, with 11 types of machine numbers № 3.15, 4, 5, 6, 7, 8, 9, 10, 11, 12, and 12.4.
At present, there is a wide range of boilers, the quality of coal used is very different, the resistance of the equipped dust collector is different, and the air pressure and air volume of the equipped induced draft fan are quite different. In order to adapt to the above conditions, considering the economy of the fan, except that the induced draft fan equipped with a 20t/h boiler adopts a D-type drive due to its large power, the rest adopt a C-type drive, which can not only meet the requirements of the same tonnage boiler equipped with various types of dust collectors at different speeds of the same machine number, It reduces the serial number of the fan, and it is also convenient for the user to change the rotation speed of the main shaft according to the actual situation to obtain the desired air volume and air pressure.
Y5-48 boiler-induced draft fan structure
Y5-48 boiler-induced draft fans can be made into two types: right rotation or left rotation. When the fan is viewed from the motor end, if the impeller rotates clockwise to turn right, it is indicated by "right"; if the impeller rotates counterclockwise, it is indicated by "left".
The outlet position of the Y5-48 boiler-induced draft fan is expressed by the outlet angle of the casing. The "clockwise" and "counterclockwise" fans can be made into three angles: 0 °, 90 °, and 180 °.
The rotation mode of the Y5-48 boiler-induced draft fan is C type, and D type and the connection of the motor and fan is directly rotated by pulley and elastic coupling.
Y5-48 boiler-induced draft fan is mainly composed of an impeller, casing, air inlet, regulating valve, and transmission unit.
Y5-48 boiler-induced draft fan is a single suction fan.
Impeller: composed of 12 backward inclined flat blades made of Q345 (16Mn), welded between the arc front plate and the flat rear plate. The formed impeller has passed the static and dynamic balance tests, so it runs smoothly, has high strength and wear resistance, and has a long service life.
Casing: welded with steel plate to form a spiral case. № 8 above "right" and "left" turn to general use.
Air inlet: the converging-diverging air inlet is made into an integral structure and fixed on the inlet side of the casing with bolts.
Drive set: the main shaft is made of high-quality steel. It adopts a ball bearing, two parallel bearing seats, lubricated with No. 2 calcium-sodium base grease or molybdenum disulfide grease, and self-cooled fan blades, with a simple structure.
Regulating valve: Y5-48 is equipped with regulating valve to regulate the flow of the fan. The regulating valve is installed in front of the air inlet axially. It is flexible and convenient due to the external transmission structure. The adjustment range is from 90 degrees (fully closed) to 0 degrees (fully open). The handle of the regulating valve above № 8 is on the right side from the air inlet. Push the handle of clockwise rotation fan from bottom to top, from full close to fully open, and pull the handle of counterclockwise rotation fan from top to bottom from full close to full open.
In order to make all parts of the regulating valve work normally, it must be well-lubricated. For the induced draft fan, due to the high gas temperature, the lubricating grease adopts high temperature (260 ºC) lubricating grease, which can still ensure the lubricating effect during high-temperature operation.
Y5-48 boiler-induced draft fan installation
Precautions for installation of Y5-48 boiler-induced draft fan
1. Before installation, all components of the fan shall be comprehensively inspected. For example, whether the machine parts are complete, whether the connection of each part is tight, whether the main machine parts such as impeller, main shaft, and bearing are damaged, and whether the transmission set is flexible. If problems are found, they should be repaired.
2. During installation, pay attention to check that there are no tools or sundries falling into or left in the casing. In order to prevent rusting and reduce the difficulty of disassembly, some joint surfaces should be coated with lubricating grease or mechanical oil. The joint surface between the fan and the foundation and the joint surface of the inlet and outlet air pipes shall be carefully adjusted to make them match naturally, and the forced connection is not allowed, and the pipe weight is not allowed to be added to each component of the fan, and attention shall be paid to ensuring the horizontal position of the fan.
Installation requirements:
(1) Install according to the position and size are shown in the drawing. In order to obtain high efficiency, especially ensure the axial and radial clearance data between the air inlet and the impeller.
(2) For V-belt drive, the groove corresponding to the V-belt pulley of the main shaft and the V-belt pulley of the motor shall not be misaligned. After the tape is put on, the safety cover (made by the user) shall be installed for safety.
(3) For the coupling drive, the different centricity of the fan main shaft and motor shaft, and the non-parallelism of both ends of the coupling shall not exceed 0.05mm.
(4) When installing the regulating valve, be careful not to install it in the reverse direction, and ensure that the air inlet direction is consistent with the impeller rotation direction.
(5) After the installation of the fan, try to move the drive set to check whether it is too tight or scratched with the fixed part. If there is any, it should be eliminated.
Y5-48 boiler-induced draft fan maintenance
1. Regularly remove the dust and dirt inside the fan, especially on the blades, according to the service conditions to prevent corrosion.
2. The lubricating oil in the bearing box must be replaced once every six months under normal conditions, except during machine repair.
3. During operation, check whether the bearing temperature is normal, and the bearing temperature rise should be less than 40 ºC.
4. When the fan is started, stopped, or operated if abnormal conditions such as abnormal noise, vibration and smell are found, it shall be stopped immediately for maintenance.
5. In order to ensure personal safety, the maintenance of the fan must be carried out during shutdown and power failure.

Our company has introduced the latest research results of the Chinese Academy of Sciences, C4-II ternary flow wing twisted blades, which have high aerodynamic efficiency.
The surface of the ventilator impeller blade is sprayed with advanced super-resistant (CN) metal material to form a wear-resistant, anti-corrosion protection layer on the surface of the blade. The wear resistance of the blade surface is 10 to 50 times higher than that of the ordinary carbon steel material, thereby greatly prolonging the service life of the blade.
After we have absorbed the advantages of many domestic blade structures, based on the optimal control theory of concentrated parameters and distributed parameters, adopting the advanced ternary flow theory of impeller machinery and perfect CAD design technology, through multi-parameter control by blade bending amount, this blade is a high-performance fan blade. It ensures that the ventilator is operating in a wide and efficient area on the premise of meeting the wind volume and wind pressure.
Our company adopts computer simulation calculation and quasi-ternary flow theory, we correct the blade shape and calculate coordinate parameters of its shape, then make the core mold and the external pressure mold of the blade, and the blades are formed by hot pressing. According to a large number of experiments, the tilting blade has a larger lift-to-drag ratio than the original organic blade type and is the best choice for the airfoil blade.
The blades are welded with high-strength carbon steel material. The petiole is treated with high-quality carbon steel. So that the blade maintains the strength and rigidity of the steel blade when ensuring the corrosion resistance and wear resistance of the blade. Moreover, it effectively protects the blade from corrosion resistance and wear resistance in a humid air environment, and improves the operating life of the ventilator.
The surface of the blade is coated with a super-resistant (CN) metal material coating, which not only maintains the strength and rigidity of the high-quality carbon steel blade, but also effectively protects the blade from corrosion resistance and wear resistance in a humid air environment, and improves the operating life of the ventilator.
The petiole is forged and made of high-quality medium carbon steel, and the tempering heat treatment is performed. The root has enough transition arc to eliminate stress concentration, through reasonable and correct force analysis and calculation, the strength, and safety factor of the most dangerous section of the blade root is more than 6 times. And carry out 100% X-ray non-destructive testing for welding seams of the blade root section and the blade, and all the defects were eliminated. Therefore, the impeller has a high degree of operational safety. Since the supply of the ventilator produced by our company, there has never been an accident of the petiole breaking and flying blades.
The impeller hub is made of high-quality steel and then tempered to process heat treatment. The surface of the hub is processed into a spherical shape, the petiole hole is placed at the thickest part of the center of the rim, which reduces the friction loss of the wind flow and ensures that the force-bearing section of the hub has sufficient tensile strength and rigidity. The welded joints of the hub all adopt groove welding and carry out 100% X-ray non-destructive testing for welding seam, which ensures the safe operation of the impeller.
After the blade is formed, first sandblasting is performed to remove dirt on the surface of the blade such as welding slag and oxide layer, to show the original color of the metal; Then, using the latest international inverter pulse arc power supply and high-speed arc spray gun to paint the super-resistant (CN) metal material on the surface of the blade, to form a wear-resistant anti-corrosion protection layer on the surface of the blade. Compared with the traditional arc spraying equipment and spraying process, the coating is denser, the ultra-resistant (CN) metal material has higher bonding strength with the blade's basic body, and the service life is longer.
